This chapter addresses and explains the basic features for  

CRUX

TM

 including:

•   Only use the battery and charger approved for use with the CRUX

TM

. 

•   Only use the battery for the system for which it is specified. 
•   Only use or replace the battery with a charging system or another battery that has been qualified with the 

system per this standard, IEEE-Std-1725-2006. Use of an unqualified battery or charger may present a risk of 
fire, explosion, leakage, or other hazard. 

•   Only use the battery for its original purpose. As an improper battery use may result in a fire, explosion or 

other hazard.

•   Try to keep batteries in a temperature between 41°F (5°C) and 95°F (35°C). If the battery is stored in 

temperatures above or below the recommended range, give it time to warm up or cool down before using.

•   Store the discharged battery in a cool, dark, and dry place.
•   Purchase a new battery when its operating time gradually decreases after fully charging.
•   Properly and promptly dispose of the battery according to local laws.
•   Battery usage by children should be supervised.

•   Don’t attempt to disassemble or open the battery – it is a sealed unit with no serviceable parts.
•   Don’t crush, bend or deform, puncture or shred the battery.
•   Don’t drop the phone or battery. If the phone or battery is dropped, especially on a hard surface, and the user 

suspects damage, take it to a service center for inspection. 

•   Don’t leave the battery in extremely hot or cold temperatures. Otherwise, it could significantly reduce the 

capacity and lifetime of the battery.

•   Don’t modify or remanufacture, attempt to insert foreign objects into the battery, immerse or expose to water 

or other liquids, expose to fire, explosion or other hazard. 

•   Don’t accidentally short-circuit the battery by carrying it in your pocket or purse with other metallic objects 

such as coins, clips and pens. This may critically damage the battery.

•   Don’t short-circuit a battery or allow metallic conductive objects to contact battery terminals.
•   Don’t dispose of the battery by placing into a fire.
